Trajan's Column

Today, the Column of Trajan is the most prominent architectural feature of Trajan's Forum, left nearly intact but now isolated from its original setting. The Column was placed toward the northernmost point of the forum, acting as the focal point of the entire forum complex. It was surrounded on three sides by two flanking libraries and the Basilica Ulpia. The two libraries to the northeast and southwest of the Column were for the study of scrolls written in both Latin and Greek.[13] These libraries were built in tandem with the Column.[14] They apparently included upper level viewing platforms for two sides of the column. By having an elevated vantage point, the figures of the scenes, carved in shallow relief and detailed with paint and metal fittings, could be seen more closely (nevertheless it remained impossible for the ancient viewer to follow sequentially the continuous spiral of the reliefs). The problem with visibility of the upper areas is further apparent when we compare Trajan's Column to the Column of Marcus Aurelius. The figures in the later Column of Marcus Aurelius are more deeply cut and even simplified over the height of the shaft because there were no surrounding buildings to serve as viewing platforms. The different carving style seems to have been adopted to enhance visibility.

The two libraries flanking the Column helped to further the emperor's program of propaganda. In addition to serving as viewing platforms for the Column, they housed valuable works of literature for the people of Rome. Surely one important text kept here was Trajan's own account of the Dacian Wars, now lost. The reliefs on the Column documenting the Dacian campaigns would have provided a vivid complement to Trajan's account of the wars. The people of Rome were reminded of his victories every time they enjoyed the open space and amenities of the forum.[15] The combination of the Column and the magnificent buildings that surrounded it created an awe-inspiring spectacle.

Battle scene between the Roman and Dacian armies

It is unclear whether the Column was meant to serve a commemorative function or as a propaganda piece. Traditional scholarship held that the Column was a glorifying monument, upholding Trajan as Rome's great emperor. However, recent reconstructions of Trajan's Forum have determined that any wide view of the Column would have been mostly obstructed by two libraries in the Forum which tightly bookended it. Also, because it would have been difficult to follow the spiral frieze from end to end (walking in circles with head inclined), the Column's narrative power would have been fairly limited.

On the other hand, as French archaeologist Paul Veyne notes, the relief could be read "vertically" from below, with the figure of the emperor recognizable across the bands of images—just as, on the Colonne Vendôme, Napoleon's figure can be picked up, scene after scene. Additionally, the two libraries surrounding it provided platforms from which to observe the Column if the viewer stood on the top floors, making the complete view of frieze much more visible.

Trajan's Column around 1896

While there is certainly evidence that the Column was not put in an ideal spot for visibility, it is impossible to reject the Column as some form of a glorification structure. There is the significant point that the Column was extremely challenging to construct, and so it is unlikely that it would have been placed in the Forum with the intentions of being hidden or out of plain sight.[16]

There is also the important idea of the Column as a symbol for Trajan. Trajan's ashes were buried in a chamber at the base of the Column. At the top of the Column was a statue of Trajan. The ground level of the Forum, which is a center of life for Romans, is where the earthly remains of Trajan are buried. The Column from the base goes up, taking a viewer through Trajan's triumph in the Dacian wars, and (as originally constructed) finishes with a statue of Trajan above the forum. Considering the practice of deification of emperors which was expected during this time period, especially of glorious Trajan, the symbolism may be interpreted as Trajan's earthly remains staying in the Forum with the Roman people while his conquests ascend him up into the heavens.[16]

The Column acting as a funerary monument has also been considered. After Trajan's death in 117, the Roman Senate voted to have Trajan's ashes buried in the Column's square base, which is decorated with captured Dacian arms and armor. His ashes and those of his wife, Plotina, were set inside the base in golden urns (which later disappeared from the monument). One reading of this is that Trajan may have intended the Column to be his final resting place from the project's inception, and that the similarities in design to other funerary structures made it a natural choice for the Roman Senate.[17] In particular, the circumambulation demanded of onlookers of the Column's frieze is evocative of Roman funerary practice, drawing attention toward the center – and consequently, the finial of Trajan.

Perhaps the simplest interpretation is provided by the inscription written above the entrance (translated below): that the mere existence of Column was an engineering marvel due to the immense excavation efforts necessary for its construction.[18]

The inscription plate above the entrance to the interior (upper image)

The inscription at the base of the column in finest lettering reads:

SENATVS·POPVLVSQVE·ROMANVS

IMP·CAESARI·DIVI·NERVAE·F·NERVAE
TRAIANO·AVG·GERM·DACICO·PONTIF
MAXIMO·TRIB·POT·XVII·IMP·VI·COS·VI·P·P
AD·DECLARANDVM·QVANTAE·ALTITVDINIS

MONS·ET·LOCVS·TANT<IS·OPER>IBVS·SIT·EGESTVS

Translated, the inscription reads:

The Senate and people of Rome [give or dedicate this] to the emperor Caesar, son of the divine Nerva, Nerva Traianus Augustus Germanicus Dacicus, pontifex maximus, in his 17th year in the office of tribune, having been acclaimed 6 times as imperator, 6 times consul, pater patriae, to demonstrate of what great height the hill [was] and place [that] was removed for such great works.

It was believed that the column was supposed to stand where the saddle between the Capitoline and Quirinal Hills used to be, having been excavated by Trajan, but excavation has revealed that this is not the case. The saddle was where Trajan's Forum and Trajan's Market stood. Hence, the inscription refers to the Trajan's entire building project in the area of the Imperial fora.

This is perhaps the most famous example of Roman square capitals, a script often used for stone monuments and, less often, for manuscript writing. As it was meant to be read from below, the bottom letters are slightly smaller than the top letters, to give proper perspective. Some, but not all, word divisions are marked with a dot, and many of the words, especially the titles, are abbreviated. In the inscription, numerals are marked with a titulus, a bar across the top of the letters. A small piece at the bottom of the inscription has been lost.

The typeface Trajan, designed in 1989 by Carol Twombly, uses letter forms based on this inscription, working from the research of Edward Catich. There have been many other typefaces based on the inscription from such designers as Frederic Goudy and Warren Chappell.

The interior of Trajan's Column is hollow: entered by a small doorway at one side of the base, a spiral stair of 185 steps gives access to the platform above, having offered the visitor in antiquity a view over the surrounding Trajan's forum; 43 window slits illuminate the ascent.[19]

The column stands 38.4 m (126.0 ft) high from the ground to the top of the statue base:[20] Located immediately next to the large Basilica Ulpia, it had to be constructed sufficiently tall in order to function as a vantage point and to maintain its own visual impact on the forum.[21] The column proper, that is the shaft without the pedestal, the statue and its base, is 29.76 metres (97.64 feet) high, a number which almost corresponds to 100 Roman feet; beginning slightly above the bottom of the base, the helical staircase inside measures a mere 8 cm (3 in) less.[22]

The column is composed of 29 blocks of Luni marble, weighing in total more than 1100 t.[20] The spiral stair itself was carved out of 19 blocks, with a full turn every 14 steps; this arrangement required a more complex geometry than the more usual alternatives of 12 or 16.[23] The quality of the craftsmanship was such that the staircase is practically even, and the joints between the huge blocks still fit accurately.[24] Despite numerous earthquakes in the past, the column today leans at an angle of less than half a degree.[24]

Trajan's Column, especially its helical stairway design, exerted a considerable influence on subsequent Roman architecture. While spiral stairs were before still a rare sight in Roman buildings, this space-saving form henceforth spread gradually throughout the empire.[25] Apart from the practical advantages it offered, the design also became closely associated with imperial power, being later adopted by Trajan's successors Antoninus Pius and Marcus Aurelius. In Napoleon's time, a similar column decorated with a spiral of relief sculpture was erected in the Place Vendôme in Paris to commemorate his victory at Austerlitz.

Erection of the Vatican obelisk in 1586 by means of a lifting tower. A similar arrangement was presumably used for the construction of Trajan's Column, but with less available space and thus manpower.

It is assumed that the column drums were lifted by cranes into their place.[3][26] Ancient sources, as well as a substantial body of archaeological evidence, show that Roman engineers were capable of raising large weights clear off the ground. The typical drum of Trajan's Column weighs c. 32 t,[2] while the capital, the heaviest block above the base and pedestal, is even at 53.3 t, which had to be lifted 34 m high.[3] To save weight, the treads had probably been carved out before either at the quarry or in situ.[24][27]

Even so, for such loads, the typical Roman treadwheel crane, which could only reach a maximum height of 15 to 18 metres (49–59 feet) in any event, was clearly inadequate.[3] Instead, a tower-like wooden construction was erected around the building site, in the midst of which the marble blocks were raised by a system of pulleys, ropes and capstans; these were powered by a large workforce of men and possibly also draught animals, spread out on the ground.[28] According to modern calculations, eight capstans were needed to hoist the 55 t base block, while the length of rope required for the highest drums measured some 210 metres (690 feet) assuming two-block pulleys.[29]

Such a lifting tower was later also used to great effect by the Renaissance architect Domenico Fontana to relocate obelisks in Rome. From his report, it becomes obvious that the coordination of the lift between the various pulling teams required a considerable amount of concentration and discipline, since, if the force was not applied evenly, the excessive stress on the ropes would make them rupture.[30] In case of Trajan's Column, the difficulties were exacerbated even further by the simultaneous work on the neighbouring Basilica Ulpia, which limited the available space so that the capstan crews had proper access only from one side.[31][32]

The plaster casts laid out at eye level in the Museum of Roman Civilization

Plaster casts of the relief were taken in the 19th and 20th centuries. After a century of acid pollution, they are now more legible in some details than the original, and the way they are displayed offers students a closer look at the reliefs than at the original site. Examples can be studied at:

• Museum of Roman Civilization in Rome, where each "frame" of the narrative has been cut into a separate section and the sections are then displayed horizontally in order
• National Museum of Romanian History, Bucharest, Romania, which displays the frieze horizontally in segments
• Cast Courts at the Victoria and Albert Museum, London. Displayed in column form and, including the base, the column is chopped into two halves.
• Archaeological Collection of the University of Zürich, University of Zürich

Additionally, individual casts of the frieze are on display in various museums, for example, in the Museum for Ancient Navigation in Mainz. A complete survey in monochrome was published by the German archaeologist Conrad Cichorius between 1896 and 1900 (see Commons),[33][34] still forming the base of modern scholarship.[35] Based on Cichorius's work, and on the photographic archive of the German Archaeological Institute, a research-oriented Web-based viewer for Trajan's Column was created at the German-language image database.[36]
